Problem

settings.py

INSTALLED_APPS = [
    ...
    'django_select2',
]

CACHES = {
    "default": {
        "BACKEND": "django.core.cache.backends.locmem.LocMemCache",
        "LOCATION": "unique-snowflake",
    },
    "select2": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/2",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        },
    },
}

SELECT2_CACHE_BACKEND = "select2"

main urls.py

urlpatterns = [
    ...
    path('select2/', include('django_select2.urls')),
    ]

app models.py

class Clients(models.Model):
    name = models.CharField(max_length=150, blank=True)
    phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$')
    phone = models.CharField(validators=[phone_regex], max_length=17)
 
    def __str__(self):
        return self.phone

app forms.py

class PhoneSelect2Widget(s2forms.ModelSelect2Widget):
    search_fields = ('phone__icontains',)
    queryset = Clients.objects.all()

class RelatedAddForm(forms.ModelForm):
    phone = forms.ModelChoiceField(
        widget=PhoneSelect2Widget(attrs={'class': 'select2'}),
        queryset=Clients.objects.all())

    def __init__(self, *args, **kwargs):
        self.request = kwargs.pop('request', None)
        super(RelatedAddForm, self).__init__(*args, **kwargs)

    class Meta:
        model = Clients
        fields = ['phone']

base.html

{% load static %}
<html lang="en">
    <!--begin::Head-->
    <head>
        <title>HUB CRM</title>
        {{ form.media.css }}

Hi @lapitskiy,

Thank you for reaching out. Would you mind sharing the HTML for the screenshot, or at least the relevant parts? Otherwise, my guesses might be more confusing than helpful.

Best,
Joe

hi,

I can't find the django-select2.min.js nor the select2.min.js script in your HTML output. Can you check if it's there? From I am seeing now, it looks like Select2 has not been initialized. If the script is missing, that would explain things.

Cheers!
Joe
